A 15-yr-old, male lesser Madagascar hedgehog tenrec (Echinops telfairi) presented with a mass caudal to the right ear. Cytology suggested a sarcoma. Surgical removal was attempted. Histology was consistent with a soft tissue sarcoma. The mass recurred within 331 days post operation. Radiation
The authors reviewed the Massachusetts General Hospital experience with primary malignant stromal tumors of the gastrointestinal tract since 1962. Fifty-one of fifty-five lesions were leiomyosarcomas, and the most common anatomic location was the stomach (47%), followed by small intestine (24%),
The efficacy of desacetyl vinblastine amide (DVA) was tested against five human sarcomas heterotransplanted into nude mice. Marked antitumor effect was found against a lipoblastic liposarcoma, including complete regressions of tumor in some animals. A lesser, though statistically significant,
We report the F-18 fluorodeozyglucose positron emission tomography computed tomography appearance of a biopsy-proven primary gastric sarcoma in a 24-year-old man who presented with early satiety, dyspepsia, and weight loss. Gastric sarcoma is a rare form of malignancy constituting approximately 0.3%
Administration of sheep anti-mouse interferon serum or globulin to weanling BALB/c mice infected with Moloney sarcoma virus (MSV) accelerated the growth of tumours at the site of virus inoculation, increased the number and size of tumours, and inhibited their regression. The outcome of the
Treatment by glucosamine of avian sarcoma virus-transformed chicken embryo fibroblast (CEF) cells completely inhibited the formation of progeny-transforming virus particles. Such cells, however, could continue to synthesize non-infectious physical particles containing both viral RNA and the enzyme
The caseinolytic activity of several strains of Rous sarcoma virus (RSV), conditional and nonconditional mutants of RSV, and nontransforming avian leukosis viruses was investigated. Only those viruses capable of transforming chick fibroblasts in vitro induced lysis of casein incorporated into an
Epidemic acquired immune deficiency syndrome-related Kaposi's sarcoma (AKS) in tropical and southern Africa is a highly varied neoplastic disease, characterized by multifocal mucocutaneous, lymphatic and visceral involvement. It follows a clinical course similar to AKS in Europe and the USA.
During the past decade, local control of primary sarcomas of the extremities by radiation and conservative surgery has supplanted more radical compartmental resections or amputations. Reviews of others and our published data show that the probability of achieving local control is highly dependent on
Fifteen patients with surgically incurable, advanced, and metastatic sarcomas were treated with courses of adriamycin and vincristine-actinomycin D alternating within a 7-week cycle. Three patients had objective partial responses for more than 3 months (liposarcoma, 4 months; fibrous histiocytoma,
We report a case of a 36-year-old lady who presented with a huge fungating tumour that involved the entire right breast. The tumour was diagnosed histologically as undifferentiated primary stromal tumour of the breast with axillary lymph node metastasis. We review the literature of this rare
The present report describes an in vitro culture system using the Kirsten murine sarcoma virus transformation focus assay to evaluate the antiviral activities of 12 commonly used chemotherapeutically effective drugs. Since these drugs are cytotoxic, the plating efficiencies of the cells treated were
A RNA-directed DNA polymerase was partially purified from a human homologous, mixed mesodermal sarcoma by DEAE-cellulose chromatography after sucrose density centrifugation. The enzyme transcribed poly(rA) most effectively but also transcribed poly(rI), poly(dA) and poly(rG) and to a lesser extent,
The preoperative use of chemotherapy in the management of soft tissue sarcoma is a recent concept in the multidisciplinary management of neoplasia related to the development of more effective drug combinations. The reason for chemotherapy preoperatively is to define the effectiveness of drug
Extra-hepatic Walker sarcoma 256 produced a marked decrease (approximately 60%) in the levels of cytochrome P-450 and NADP-cytochrome P-450 reductase in rat liver endoplasmic reticulum, and a lesser decrease (approximately 20%) of cytochrome b5 and NADH-cytochrome b5 reductase. Polychlorinated
